Get the POSIX flags and the QNX Neutrino extended flags from a spawn attributes object
#include <spawn.h> int posix_spawnattr_getxflags( const posix_spawnattr_t *_Restrict attrp, uint32_t *_Restrict flags_p);
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The posix_spawnattr_getxflags() function retrieves the POSIX flags and QNX Neutrino extended flags from the spawn attributes object pointed to by attrp, and stores them in the object pointed to by flags_p. You must have already initialized the spawn attributes object by calling posix_spawnattr_init().
POSIX defines the following flags:
QNX Neutrino defines the following extended flags:
These flags indicate which process attributes you want to change in the new process image when you invoke posix_spawn() or posix_spawnp(). For detailed information about the flags, see the entry for posix_spawn().
![]() |
The posix_spawnattr_getxflags() function is a QNX Neutrino extension. POSIX specifies the posix_spawnattr_getflags() and posix_spawnattr_setflags() routines, which get and set only the POSIX flags. |
